CONSECUTIVE SHOOTING
While the shutter release button is held down, a trame is
shot every 1 3 sec. The camera focuses on the subject
frame-by-frame during this operation, so the autofocus
frame (^ ^) should be kept on the subject during
shooting.
Note:
• When using the flash, shooting intervals become longer
due to the flash recharging.
This mode allows the photographer to expose multiple
images on the same frame in a variety of imaginative
ways.
